Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus which outputs karaoke accompaniment music as an acoustic sound and displays a lyrics image accompanied by an appropriate background image. The present invention relates to a background image selection system for selecting and displaying a suitable background image from a common image database.

[0002]

2. Description of the Related Art In a general communication type karaoke apparatus, a background image peculiar to each music is not provided, but a common background image recorded on a CD-ROM or a DVD-ROM is shared for each music. It reuses. At that time, we have made various efforts to prevent an extreme mismatch between the content and atmosphere of the music and the background image.

For example, there is a method in which a background image to be used for each music is determined in advance and background selection data for sequentially designating a video section to be displayed on the performance time series of the karaoke music is attached to the karaoke data of each music. is there. According to this method, a fixed background image is always displayed when a certain piece of music is played.

In another method, a music genre descriptor (classification of ensemble, pops, folk songs, etc.) is added as index information of the karaoke database, and each picture section of the background picture database is used for ensemble pictures and pops. A method has been adopted in which a music genre descriptor such as an image or a folk song image is added, and a background image suitable for the music genre of a music piece to be played is randomly selected and displayed. According to this method, different background images are displayed each time the same song is played.

[0005]

Assuming a communication karaoke system in which the contents of the background video database are gradually increased, the latter method, in which the music and the background video are not fixedly connected, will be enriched. It is excellent in that video contents can be used for existing music. Recently, copyrights have been added to incorporate new videos that are produced one after another into karaoke background images, and to incorporate stored past images such as old movies, TV programs, or news images into karaoke background images. The environment related to the problem is improving. In addition, progress in storage / playback technology and communication technology related to digital video has also contributed to the enrichment of karaoke background video.

[0006] Viewing the background image of karaoke is a great enjoyment, especially for those who are listening to the song.
Enriching this background image with a rich content will greatly enhance the commercial value of karaoke.

The era is often talked about in the scene of enjoying karaoke. For example, many people may have sung karaoke in a group of the same age group, and had the experience of having a lively conversation about the events and memories of the time when the song was popular. In such a scene, when a certain song is sung and the background image is suitable for that song, it will spur the excitement of the memory of karaoke.

The present invention has been made based on the above viewpoints, and its purpose is to select a background image suitable for an era when individual songs became popular or became a topic from a shared image database. To provide a background image selection system in a karaoke device that can be displayed and can be immediately reflected in the user service that the contents of the background image database are being added and enriched. is there.

[0009]

[Means for Solving the Problems] A first invention for achieving the above object is to add an era descriptor indicating an era when each song became popular or became a topic as index information of a karaoke database. Every time, as the index information of the background video database, a genre descriptor corresponding to each video content is added to each video section with a semantic cohesion, and each video section with a temporal cohesion recalled by the video content When an audio image is output synchronously with the accompaniment music and the lyrics image based on the karaoke data of a certain song selected from the karaoke database, the period of the song in the index is added. The index of the background video database is searched based on the descriptor and the genre descriptor appropriately selected, and the period as a search key is searched. A background video selection system in a karaoke device, characterized in that a video section that matches the descriptor and the genre descriptor is selected, and video data of the video section is retrieved from the background video database and displayed as the background of the lyrics video. And

The second invention is based on the first invention.
When searching the index of the background image database, first, the period descriptor added to the music is used as a key, and a plurality of image sections that match this are selected (primary selection), and these primary selections are made. A plurality of types of the genre descriptors assigned to the selected video section are presented to the user as options, and the video section corresponding to the genre descriptor selected by the user is selected from the primary selected video sections. The background image selection system in the karaoke device is characterized in that it is selected as the background image to be displayed from.

The third invention is based on the first invention.
When searching the index of the background video database, the list of the genre descriptors is presented to the user as an option to have the user select a specific genre descriptor, and the genre descriptor and the music assigned to the music are described above.

Alternatively, a display 9 using a PDP or the like and a video processing device 10 for processing video data to be displayed on the display 9 are provided. C
A large number of CD-ROMs are detachably mounted in the D-ROM reproducing device 3, and a plurality of disk drives for selectively reproducing these disks by a changer are provided.

=== Database Configuration Example === The karaoke apparatus of this embodiment has a karaoke database and a background video database, and the central processing unit 1
Manages the ledgers for these databases by creating them in the hard disk device 2.

The karaoke database is constructed by using the hard disk device 2, the CD-ROM reproducing device 3 and the DVD-ROM reproducing device 4 as storage resources, and stores karaoke data for many songs including music performance data and lyrics data. The song ID is used as a key for centralized management. In particular, in this embodiment, the index information in the ledger of the karaoke database is represented by an era when each song became popular or became a topic (represented by a year, month, or a period of several years to several decades, and comparisons before and after each other are possible. Is added).

The background image database is constructed by using the CD-ROM reproducing device 3 as a main storage resource, and the MPEG produced and edited by a live-action moving image or a CG image.
This database contains long-term background image data such as formats. The background video data can be specified by being divided into short sections by a section ID such as a disc number and a track number. That is, a large number of video divisions are aggregated and managed using the division ID as a key. Particularly, in the present embodiment, the section ID of the start point and the section ID of the end point in the specific section (video section) of the background video data.
It is managed by section information consisting of.

A logical structure of index information in the ledger of the background image database created and managed in the hard disk device 2 by the central processing unit 1 is illustrated in FIG. The index information includes two types, a genre index table and an age division index table. The genre index table assigns genre descriptors assigned based on the content (genre) of background images such as spring, summer, autumn and winter, sports, and cooking.
It is recorded in association with the section information of the background video data. The era section index table is a table in which era descriptors assigned based on the era represented by the background video are recorded in association with the section information of the background video data.

=== Basic processing of karaoke data === When the central processing unit 1 receives a request for music through the user interface device 6, it manages music IDs in a queue in the order of request input. . When the ID of the music piece to be played is determined, the karaoke data corresponding to the music piece ID is retrieved from the karaoke database, and the included music performance data is transferred to the music generation device 7 to generate the accompaniment music. The generated accompaniment music and the singing voice of the singer collected by the microphone are mixed by the acoustic device 8, and the sound is output from the speaker. Prior to the series of accompaniment music generation processing, background image selection processing, which will be described later, is performed, and the selected background video is displayed on the display 9 together with the lyrics video in which the color of the portion to be sung is changed.

=== Selection of background image === When the music to be played next is determined by the management of the performance queue, the central processing unit 1 starts to prepare for the performance of the music,
The era descriptor included in the music index information is extracted and compared with the era section index table of the background video data described above. Then, the video section in which the period descriptors match or overlap is taken out and the section information is temporarily stored in the RAM or the like.

Next, regarding the video section that coincides with or overlaps with the era descriptor of the karaoke piece, the genre descriptors assigned to all or part of the section are extracted by referring to the genre index table, and section information is obtained. It is temporarily stored with. Then, the genres such as spring, summer, autumn and winter, sports, and dishes corresponding to the extracted genre descriptors are displayed in a list on the display 9 and presented to the user, and the background desired by the user based on a predetermined user interface. Select and enter the video genre.

For example, assuming that a, b, c, d, e, f, g and h as the classification IDs of the background image data are temporally later in this order, they coincide with or overlap with the era descriptor of the karaoke piece. In the video section, the section ID of the start point is b, the section ID of the end point is d (that is, the section information of this video section is b to d), the section ID of the start point is f, and the section I of the end point is I.
It is assumed that D is two sections of h (section information is f to h).
On the other hand, according to the genre index table, the section information of the video section of the genre descriptor A is ac, the section information of the video section of the genre descriptor B is c to e, and the section information of the video section of the genre descriptor C is The section information is e to g. At this time, the genre descriptor A (the section information is b to
c), B (section information is c to d), C (section information is f to d)
g) is taken out, and the genres corresponding to A, B, and C are presented to the user.

When the user selects and operates (for example, the genre corresponding to the genre descriptor B in the above example),
The genre descriptor (B in the above example) corresponding to the selected genre is transmitted to the central processing unit 1. This allows you to select not only the genre of the background image you want to display according to the content of the selected karaoke song, but also the background video of the song with summer theme as the top 10 news at the end of the era. It is also possible to select the genre of the background image of your choice irrespective.

When the central processing unit 1 receives the genre descriptor (B in the above example), the corresponding video section (the video section of the classification IDs c to d in the above example) is taken out and transferred to the video processing apparatus 10. Display processing is performed on the display 9 as a background image of the lyrics image.

If the user does not perform a predetermined selection operation, one video section may be randomly selected from the ones presented to the user.

Regarding the background video data, the video section based on the era descriptor and the video section based on the genre descriptor do not always match, as in the above-described example. Regarding the video section to which one period descriptor is added, for example, the video of a news program contains various contents such as sports news, weather, introduction of new products, etc. Descriptor may be attached. On the contrary, in the case of following the transition of the same content in a history program, the genre descriptor may include multiple period descriptors even in one video section. this is,
This is because the period descriptor and the genre descriptor are different classification scales for the same background video data.

=== Other Embodiments === In this embodiment, when the music piece to be played is determined, a video section that matches the period descriptor of the music piece is first extracted from the background video data, and the desired video section is selected from the video section. We adopted a method that allows the user to select the genre of the video, but first let the user select the genre of the desired video and then select the one that matches the period descriptor of the song from the video section of that genre. The method of doing may be adopted. You can also select the genre when you reserve a song, you can select the genre after the song to be played is decided, and you can always select and change the genre regardless of the playing order of the song. You may keep it.

In any case, if there is no video section that matches the period descriptor of the music in the video section extracted based on the genre descriptor, the era descriptor of the music or the genre selected by the user You may re-select a video section that matches one of the descriptors from the background video data, or store in advance a video for each genre that does not relate to the era, or a landscape image that does not relate to the era or genre. It may be used in advance.
